I need 12 pulse out of my midio128

[toxictv101]

hi ,

i have build some tr808 sound modul

and with it a midio128 that produce 1ms trig out

i also have add a din Roland sync 24 Output to be able to ctrl Roland gear with the BoX.

the problem is that , it have to send 12 x 1ms pulse to get one step out of the sequencer

so i would like to modifi the midio128 prog to make it send (only on 1 pin)

12 x 1ms pulse (12pulse @ 500hz) eatch time i send a note to it by midi

so the roland sequ. can understand that he got to play a step

Any one Can help me , show me how to include this in the soft ?

Tks

There was something similar done to run gameboy sync... might be worth a search... Yeh that one :)

yep but its not done in the midio128 but in the sync box :s

Oh so it's not the 12 pulse part that you're wondering about, but the clock itself.... Do you want it to be master only, or also slave? If you want the slave capabilities you might want to borrow code from the SEQ, otherwise just a timer should suffice... And of course you'll have to add to the CS code too. How's your ASM skills man? It won't be really simple...

for now

ive connected the start/stop pin of the Din sync  to a switch with 5 volt

and the clock pin from the din sync to a dout pin, so when the corespondant note is play

roland seq. think that its a clock pule,  i would like to configure the midio

so that it know that when these note is played, its note 1 pulse (1ms)

that it have to do , but 12. 

or other solution would be to make the midio capable of receive the midi clock

and traduce it by pulses (1 or 12 or 24 ... ) on dout.
